I think you're making way too much of this.  The question was just "why
is my existing "From_" line being altered when copying from one mbox
to another."  I say, why indeed.  In all the cases where it needs to be
fabricated, by all means, fabricate it.  Where it already exists in the
source and should also exist in the destination, try to preserve it.
That's all.
